72391663 ÷ 356 
We're looking to find how many times 356 goes into 72391663.

Let's proceed to step 1:
356 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 356

Moving on to step 2:
356 can be fit into 72 0 times, resulting in a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 356

Advancing to step 3:
356 goes into 723 2 times with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 712 from 723 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 356

Step 4:
356 can be fit into 119 0 times, resulting in a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 119 to get 119.
Grab the next digit (1) from the dividend, add it to 119, then carry on: 1191 / 356

Advancing to step 5:
When dividing 1191 by 356, we get 3 with a remainder of 123.
Put 3 as the next digit of the answer. 
Result so far: 203.0
Subtract 1068 from 1191 to get 123.
Include the next digit (6) from the dividend after 123, then repeat: 1236 / 356

Advancing to step 6:
1236 divided by 356 is 3 with a remainder of 168.
The number 3 becomes the next digit in our result. 
Result so far: 2033.0
Subtracting 1068 from 1236 leaves us with 168.
Fetch the next digit (6) from the dividend, attach it to 168 and continue: 1686 / 356

Moving on to step 7:
The number 356 fits into 1686 4 times, leaving a remainder of 262.
Use 4 as the next digit of our solution. 
Result so far: 20334.0
Subtracting 1424 from 1686 leaves us with 262.
Fetch the next digit (3) from the dividend, attach it to 262 and continue: 2623 / 356

Advancing to step 8:
2623 divided by 356 is 7 with a remainder of 131.
The next digit of our result is 7. 
Result so far: 203347.0
If we take 2492 away from 2623, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 9:
When dividing 1310 by 356, we get 3 with a remainder of 242.
The number 3 becomes the next digit in our result. 
Result so far: 203347.3
Subtracting 1068 from 1310 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 10:
When dividing 2420 by 356, we get 6 with a remainder of 284.
Record the quotient 6 as the next digit in the result. 
Result so far: 203347.36
If we take 2136 away from 2420, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 11:
When dividing 2840 by 356, we get 7 with a remainder of 348.
The next digit of our result is 7. 
Result so far: 203347.367
If we take 2492 away from 2840, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 12:
When dividing 3480 by 356, we get 9 with a remainder of 276.
The number 9 becomes the next digit in our result. 
Result so far: 203347.3679
The remainder is 276 after subtracting 3204 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 13:
The number 356 fits into 2760 7 times, leaving a remainder of 268.
Write down 7 as next digit of the result. 
Result so far: 203347.36797
The remainder is 268 after subtracting 2492 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 14:
356 can be fit into 2680 7 times, resulting in a remainder of 188.
Use 7 as the next digit of our solution. 
Result so far: 203347.367977
The remainder is 188 after subtracting 2492 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

After the division, we end up with 203347.367977 and a remainder of 1.88e-05.
